Barbotinia oraniensis (Barbotin, 1964) is here reported for the first time from Turkey. The cynipid wasp has recorded in Mediterranean region, Northern Africa and some European countries. The galls of the species were collected from the seed capsules of Papaver rhoeas L. (Papaveraceae) in April 2022. Photos of the gall, and data on the distribution, and biology of the new record species are provided.

Trabzon province attracts foreign tourists from Arab countries, and forest recreation areas are used extensively. This study aimed to determine the consumer profile, recreational use of forest resources, user and recreational demand characteristics for recreational areas, and consumer preferences and expectations of Arab tourists coming to Trabzon. In the study, a face-to-face survey was conducted with the random sampling method for 400 Arab tourists using 10 forest recreation areas in Trabzon. In the survey, questions such as visitor characteristics of foreign tourists, use of forest resources, recreational suitability, deficiencies, and reasons for site preference were included. The obtained data were evaluated with descriptive statistics, analysis of variance, and the Duncan test. According to the analyzes and evaluations, it was found that approximately 83% of Arab tourists coming to Trabzon for forest recreation tourism came from Kuwait, Jordan, United Arab Emirates, Oman, and Iraq. The most common activities in forest recreation areas were determined as walking on forest roads, chilling, watching the scenery, taking fresh air, and taking pictures. The reasons considered very important for the preference of forest recreation areas by Arab tourists were determined natural and aesthetic values, the beauty of forests, and clean and cold water to drink, respectively. The most important variables affecting the utilization of forest recreation areas are inadequate facilities and services (4 points), environmental pollution (3.41 points), crowdedness (3.38 points), adverse weather conditions (3.34 points), noise pollution (3,12 points), security (2.86 points), transportation problem (2.59 points), and inadequate pandemic measures (1.35 points). In addition, the demand for forest recreation areas differs at 95% confidence level according to age, gender, education, family size, natural and aesthetic values, clean and cold water, the beauty of forests, tour program, friend recommendation, desire to be alone with nature, pandemic measures, lack of another place to go around the city, pollution situation, promotion and facility, and service adequacy. In the study, some suggestions were made for the sustainable management of forest recreation areas, increasing the quality of recreational services, tourist satisfaction, and tourism development for Arab tourists.

This study aimed to investigate the influence of density on the fracture behavior of southern yellow pine (Pinus taeda L.) wood in radial-longitudinal crack propagation direction under mode I loading. The density of the crack-tip location for each fracture test block was determined by using an X-ray density profile analyzer. Three fracture parameters were obtained from the load-deformation curve of each fracture test block, namely fracture toughness, initial slope, and specific fracture energy. In general, the results showed that the fracture parameters were strongly influenced by the density. Crack-tip locations with higher density were found to be more resistant to crack initiation. The initial slope of the load-deformation curve increased as the crack density in the wood increased. As a result of the regression analysis, it was observed that there were positive and strong correlations between density and each fracture parameter.

Basins formed by ecological resource have several indispensable natural values for human well-being as a part of natural landscapes. In this context, determining the different ecological characteristics of the basins is important for the sustainability and management of ecological life. In this study, infrastructures approach was applied to analyze topography and land use of the Burdur Basin. At this point, the study area was determined as green, blue, yellow, and grey infrastructures and analyzed with the topography, slope, and aspect features of the study area. Image classification utilized as a part of remote sensing of Sentinel-2A satellite images, and because of the accuracy analysis, the Kappa were calculated 0.86. In the study, NDVI, NDWI and SAVI indices were used and analyzed with infrastructure systems to determine the infrastructure identification potential of these indices. As a result, it has been determined that yellow infrastructures cover more area compared to other infrastructure types, green, blue and grey infrastructures and the yellow infrastructure, respectively. According to the indices, the NDVI index has the most infrastructures identification potential for the study area. Consequently, the dominant infrastructure type in the study area was found to be yellow infrastructure. Yellow infrastructure is followed by green, blue, and gray infrastructures respectively.
